Topical Lexicon
Root Meaning and Semantic Range

Strong’s Greek 2559 conveys the idea of inflicting hurt, mistreating, or embittering another person. It encompasses both overt physical harm and the subtler injury of mind or spirit, ranging from persecution to malicious slander. The term is consistently used for hostile action toward God’s people, highlighting the conflict between righteousness and evil that threads through Scripture.

Occurrences in Acts

Acts 7:6 quotes God’s covenantal warning that Abraham’s descendants would be “enslaved and oppressed four hundred years,” linking their future suffering in Egypt to a divine plan that would culminate in deliverance.
Acts 7:19 describes Pharaoh, who “exploited our people and oppressed our fathers,” forcing infanticide. Stephen’s speech frames the Exodus affliction as a precursor to the suffering—and ultimate vindication—of the Messiah’s followers.
Acts 12:1 records Herod Agrippa’s campaign to “harm some who belonged to the church,” setting James’s martyrdom and Peter’s miraculous release in the context of ongoing opposition to the gospel.
Acts 14:2 notes that unbelieving Jews “poisoned their minds against the brothers,” showing that κακόω can target the inner life as surely as the body.
Acts 18:10 carries the Lord’s promise to Paul in Corinth: “no one will attack or harm you,” demonstrating God’s sovereign restraint of hostile powers when His purpose requires it.

Peter’s Pastoral Assurance

1 Peter 3:13 asks, “Who can harm you if you are zealous for what is good?” Peter does not deny the reality of persecution; instead, he redefines “harm” in light of eternal security. Physical mistreatment cannot derail the believer who stands within God’s favor and ultimate vindication.

Old Testament Background

The Septuagint frequently employs the same verb for Egyptian oppression (Exodus 1:11–12; 3:7). Moses’ call narrative hinges on God’s awareness of Israel’s being “mistreated,” affirming that divine rescue is sparked by covenant compassion. Acts intentionally mirrors this vocabulary to underline continuity between Israel’s past and the church’s present.

Theological Significance

1. Divine Sovereignty in Suffering: Every New Testament occurrence places suffering within the bounds of God’s foreknowledge and redemptive purpose (Acts 7:6; 12:1; 18:10).
2. Identification with Christ: Believers share in Christ’s afflictions, anticipating participation in His glory.
3. Spiritual Warfare: The term exposes a deeper conflict where opposition to God’s people is ultimately opposition to God Himself.

Practical Ministry Application

• Shepherding the Persecuted: Pastors can anchor afflicted believers in the assurance that harm is temporary and bounded by the Father’s will (Acts 18:10; 1 Peter 3:13).
• Evangelistic Boldness: The unstoppable progress of the gospel in Acts, despite repeated mistreatment, emboldens contemporary mission efforts.
• Guarding Hearts and Minds: Acts 14:2 warns that affliction may come through ideological toxicity; discipleship must therefore attend to mental and doctrinal resilience.

Christological Fulfillment

Christ endured ultimate mistreatment—betrayal, mockery, crucifixion—turning the enemy’s intent into the means of salvation. His resurrection proves that evil cannot secure the final word; thus every occurrence of κακόω in the life of the church is already answered by the empty tomb.

Eschatological Hope

Scripture closes with the promise that nothing causing hurt will enter the New Jerusalem (Revelation 21:4, 27). The term’s New Testament usage therefore carries an implicit forward look: present mistreatment is temporary, future glory is permanent.

Summary

Strong’s Greek 2559 traces a line from Israel’s bondage through the church’s persecution to the believer’s ultimate triumph. Every text employing the verb underscores that while enemies intend harm, God transforms affliction into a stage for His faithfulness, safeguarding the advance of His saving purposes and the endurance of His people.
